[Farmall] Super A belt pulley

[john hall]

Hey John, the only O-ring is the one that seals the unit against the 
transmission.

I did notice something in the parts book I found interesting. IH furnished 
protective shields for the shafts that were held on by a hose clamp. Dad 
remembers them and seems to think they came with the tractors. Gives me 
something new to look for on restored tractors! I imagine they are a bit 
hard to find as most folks probably did like my family and took them off and 
never put them back on--this includes later model tractors as well.

John
